Probreviceps
''Probreviceps'' is a small genus of brevicipitine frogs with only six members. They occur in the montane forests of Tanzania, Zimbabwe, and possibly Mozambique. They are sometimes known as the forest frogs, forest rain frogs, big-fingered frogs, or primitive rain frogs. Description ''Probreviceps'' are burrowing frogs with short limbs and direct development (i.e., there is no free-living larval stage); the eggs are deposited in burrows. Maximum snout–vent length is between in males and between in females, depending on the species. Males often have larger tympani Timpani (; ) or kettledrums (also informally called timps) are musical instruments in the percussion instrument, percussion family.

Probreviceps Rhodesianus
''Probreviceps rhodesianus'' is a species of frog in the family Brevicipitidae. At present, it is only known from three localities in the Eastern Highlands of Zimbabwe north of Mutare; it is thus endemic to that country. However, it is possible that its range extends to adjacent Mozambique. This species has many common names: forest rain frog, highland primitive rain frog, highland rain frog, and Zimbabwe big-fingered frog. Description Males grow to and females to in snout–vent length. The tympanum is clearly visible. Skin is densely granular but has no ridges nor larger warts. Males have looser gular skin than females. The cloacal opening in both sexes has an unusual, ventrally deflected position and is surrounded by deep skin folds; the functional significance of this remains unknown. Habitat and conservation Its natural habitats are primary montane forests above . It is a terrestrial species that is usually found under rotten logs or under accumulations of leaf litter, f ...

Brevicipitidae
Brevicipitidae or rain frogs is a small family of frogs found in eastern and southern Africa. As of 2020 contains 37 species in 5 genera. eb application 2013. Berkeley, CaliforniaBrevicipitidae AmphibiaWeb, available at http://amphibiaweb.org/. (Accessed: 30 November 2013). Formerly included as subfamily in Microhylidae (narrow-mouth frogs), phylogenetic research has indicated the brevicipitine frogs should be considered as a family with Hemisotidae (shovelnose frogs) as the most closely related sister taxon. Most adult brevicipitine frogs are not easily seen as they spend extended periods of time in soil or leaf litter. However, some species might be partly arboreal at times. Many species show strong sexual size dimorphism, with females being much larger than males. At least the frogs in ''Breviceps'' and ''Probreviceps'' genera breed by direct development, in which small froglets emerge from eggs without intervening aquatic tadpole phase. It is likely that the same applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sexual Selection In Amphibians
Sex is the biological distinction of an organism between male and female. Sex or SEX may also refer to: Biology and behaviour *Animal sexual behaviour **Copulation (zoology) **Human sexual activity ** Non-penetrative sex, or sexual outercourse ** Sex drive, a person's overall sexual drive or desire for sexual activity ** Sexual intercourse, also called copulation or coitus *Gender, the distinction between male and female or masculinity and femininity within an individual's gender identity **Sex and gender distinction *Human sexuality *Mating types, a distinction of gametes, whether in anisogamous or isogamous species *Sexing, the act of discerning the sex of an animal *Sexual reproduction, a process of combining and mixing genetic traits, associated with the generation of new individuals, by means of meiosis and fertilization **Genetic recombination, the process of mixing genetic traits solely, occurring both in organisms with sexual or asexual reproduction Art and entertainme ...

Amphibian Genera
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic d ...

Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Because tails are often missing or absent, especially in juveniles, SVL is seen as more invariant than total length. Even in the case of crocodiles, tail tips may be missing. Methods The measurements may be taken with dial calipers or digital calipe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
